Abstract

Abstract: Continuously variable transmission technology might improve the power and economy of the vehicles through continuous changes in the transmission ratio. At present, the metal belt type continuously variable transmission was the mainstream form. The continuously variable transmission device was innovatively designed, a new type of planetary centrifugal mechanical stepless transmission scheme was proposed, the structure and working principle of the transmission scheme was introduced, a dynamics model was established, and then a new planetary centrifugal type continuously variable transmission basic working characteristics was obtained. At the same time, the influences of different track curves on the working characteristics were compared and analyzed. The research results provide a basis for the structural design of the planetary centrifugal mechanical transmission, and verify that the planetary centrifugal mechanical transmission has the characteristics of stepless speed regulation and self-adaptive output torques.
